Technical Field
The application relates to a heating device and a heating method for a thin-wall component, in particular to an electromagnetic indirect rapid heating device and a rapid heating method for a titanium alloy thin-wall component.
Background
The titanium alloy is used as a novel light high-strength material, has the characteristics of high strength, high toughness, corrosion resistance, excellent fatigue performance, excellent high-temperature mechanical property, high strength-to-mass ratio and the like, and is widely applied to the fields of aviation and national defense. However, due to the characteristics of high yield limit, low Young's modulus, low room temperature elongation and the like of the titanium alloy, the titanium alloy is easy to crack during plastic processing, the rebound of a formed member is obvious, and the forming difficulty is extremely high.
The existing forming method of titanium alloy thin-wall components is mostly an isothermal forming process, and the process needs to heat a die to a forming temperature, so that the isothermal forming has great heat consumption, die cost and time cost because the die mass is far greater than that of the formed components. In order to solve the problem, the inventor provides a novel process for hot stamping the titanium alloy in an unbalanced state, and the unbalanced state structure is formed by rapid heating, so that the forming performance of a plate in the hot stamping process of the titanium alloy is ensured, and the production and the application of the hot stamping technology of the titanium alloy are realized.
The existing rapid heating mode mostly adopts an electromagnetic induction heating mode, and the electromagnetic heating mode is divided into two modes that a magnetic field is parallel to a plate and a magnetic field is perpendicular to the plate. Although the magnetic field perpendicular to the sheet can reach higher heating speed, the temperature uniformity of the rapid heating of the titanium alloy thin-wall sheet is difficult to reach the requirement of a hot stamping process due to the skin effect of electromagnetic induction; when a magnetic field parallel to the plate acts on the titanium alloy plate, the magnetic field is limited by the thickness of the plate and the magnetic conductivity of the titanium alloy material, so that strong vortex is difficult to generate in the plate, and the temperature rising speed of the process requirement cannot be reached. Although the heating speed can be further improved by further improving the power, the electromagnetic induction heating efficiency is low, the remarkable joule heat is brought by the improvement of the heating speed, the cost of an electromagnetic induction power supply and a water cooling pipeline is greatly improved, and the application of electromagnetic heating in the aspect of titanium alloy thin-wall plates is restricted.
In order to solve the problem that the electromagnetic induction heating is difficult to realize rapid heating, the application provides an electromagnetic indirect rapid heating method and equipment for a titanium alloy thin-wall plate, which utilize an electromagnetic induction mode to heat an annular radiation heating block which is easy to generate an eddy current effect, realize the radiation heating of the titanium alloy material plate through a high-temperature heating block and realize the indirect electromagnetic induction rapid heating of the titanium alloy thin-wall plate.
